Is the signal routing hard? I've used hardware synth modules with the college workstations, but never at home. Yes. It just appears as an ALSA midi port and a couple of audio ports, in and out. It does have a few limitations (separate capture and synth outs in ALSA would be nice, and I'd *looove* a multitimbral version), but for the money it does a lot and does it pretty well. Only downside is that the overall feel is a bit plasticky and the grey-on-greenish-metallic colour scheme can make the control labels hard to read in a certain light. Gordon

My desktop is Linux-only. I might put a FAT 32 system on an external drive if I want to share files. I don't anticipate a lot of need for that since the sessions are not compatible between Pro Tools and, well, anything. Thanks for your assistance. I'm under a deadline, so the current project will be done in Pro Tools to make sure it gets done on time. It's one song for a contest, the subission has to be in Sep. third. I have another song I want to try producing with just open-source software. Thanks, Paul _______________________________________________ No banners. No pop-ups. No kidding.

Please help the newbie set up USB interface.

by Paul DeShaw

Greetings, I am at a loss how to make JACK recognize and connect my M-Audio Ozone MIDI keyboard controller/audio interface. I have searched the archives here, as well as Ubuntu forums. Is there anywhere else I could look? So far I have been able to use the Ozone as the soundcard for some applications, including (finally) Rosegarden. I can play a MIDI file with some synth plugins. I cannot control anything from the Ozone; it is not recognized by JACK as a MIDI client. I was also getting tons of xruns, but I fiddled with the frame rate and other parameters, and it seems to be much better now. I am running Ubuntu Studio (32 bit) on an AMD 64 processor. The graphics card is a low-end ATI, built in to the cheap ECS mobo. I am at a coffee shop now and can't get the exact models. Please tell me what else you need to know. Would I be better off with another interface? This one came with my Pro Tools setup, and I would like to save money by using it in everything. If I can successfully migrate to Linux for audio, I could get rid of the Ozone (and Pro Tools! Free at last!), but would like to stick with USB so I can use it with my Apple laptop (MacBook with Intel Core Duo at 2GHz). That's what I run Pro Tools on, and, hopefully, Ubuntu Studio at some point. My needs are simple. A few vocal tracks, maybe up to 3 guitar tracks, some synth chords and bass. Pretty much just folksy, mostly acoustic stuff. It shouldn't be too hard, but I've been at it for about a year now, without success.

New version of nekobee

by Gordon JC Pearce

Hi folks I've just released a new tarball of nekobee, my TB-303 plugin for DSSI. Changes between 0.1.5 and 0.1.6 are: * the configure script doesn't look for gtk1.x any more (thanks Juuso Alasuutari) * the release times of the envelopes are tweaked to eliminate an unattractive bloppy noise on note off with certain keyboard controllers * the volume has been reduced to around 1/5 of previous versions (in line with other DSSIs), and an atan() waveshaper has been added to give it a bit of crunch and rein in the excesses of the resonant filter * the filter parameters have been tweaked to more closely reflect the sound of the "18dB/oct" filter in the 303. Try it out, have fun, and let me know if you run into any problems. Or in fact, let me know if you *don't* run into any problems ;-) Gordon

problems with jack_mixer

by Hector Centeno

Hi, I just built and installed Jack_Mixer using Fedora 7. I can't get it to run and I get this error message: $ jack_mixer Traceback (most recent call last): File "/usr/local/bin/jack_mixer", line 22, in <module> import jack_mixer_c ImportError: No module named jack_mixer_c Searching for the file I found this: $ sudo find /usr/local -name "jack_mixer*" /usr/local/share/jack_mixer /usr/local/share/jack_mixer/jack_mixer.glade /usr/local/lib/python2.5/site-packages/jack_mixer_c.py /usr/local/etc/gconf/schemas/jack_mixer.schemas /usr/local/bin/jack_mixer.py /usr/local/bin/jack_mixer Is it a problem with a Python environment variable?
